METHOD OF LUBRICATING.

SPECIFICATION forming part of Letters Patent No. 779,315, dated January 3, 1905. Application filed January 22, 1904:. Serial No. 190,219.

To all whom it may concern:

Be it known that I, WILLEBRORDUS JAMES FELIX DE RIJK, a subject of the Queenof the .Netherlands, residing at No. 95 first van den Boschstraat, The Hague, in the Kingdom of the Netherlands, have invented a certain new and useful Method of Lubricating, of which the following is a specification.

My invention relates to an improved method or process of lubricating machinery.

In endeavoring to improve the lubrication of machinery by putting cotton in the lubricators in order to limit the supply of oil I found a substance which saturated with oil and applied in the same manner will cause very important economy of lubricant, because this substance will not deliver more lubricant than is strictly necessary for the purpose, so that all waste is prevented. This substance is manufactured by me out of the wood of the species of plants called AQSG/Lynomenc Aspcra L. (Nat. fam. of the Papilionacere) and cognate species and out of the ligneous peduncle of the Agcwe L. (Nat. fam.

of the Aw tcrryllz'clacece) and cognate species by drying thoroughly and afterward rasping and sifting these kinds of wood. By this treatment I obtain a granular spongy absorbent substance looking like sawdust, consistingof vegetable fiber. Isaturate this granular mass during some time with a great surplus of oil and put it afterward upon a sieve to enable. the superfluous oil to flow away. In this manner I obtain a strong oilretaining substance which on account of the high absorbent power of these vegetable fibers contains a quantity of oil of about ten times the weight of the fibers. The product so obtained is put in the lubricators and will yield only the quantity of oil which the machinery requires and not more.

In order to prevent the fine fibers themselves from entering into the parts of the machinery to be lubricated, I apply my lubricant preferably in the following manner: The lubricator is provided at the bottom with a fine sieve. On this sieve-the absorbent containing the oil is laid and then covered with asecond fine sieve, on which a small layer of oil is applied. By the exhaust caused by the rotation or other movement of the piece of machinery the oil is drawn from the absorbent in a quantity just necessary for the purpose of lubricating, and the quantity of oil in the absorbent will be renewed from the layer of oil above the upper sieve. By lubrieating in this manner I obtain a very important economy of the lubricant, for no waste will occur, and, moreover, the advantage is obtained that the lubricant will not be directly in contact with the piece of machinery, but will first be filtered of all dirt, which will remain in the absorbent.

To get an effective exhaust, (and this is a principal thing in applying my new absorbent,) it is necessary that the way followed by the oil from the upper sieve to the piece of machinery to be lubricated is completely isolated from the surrounding atmosphere. The lubricators have to be constructed hermetically closed, with exception of a hole in the covering for the entrance of the air and a hole in the bottom for the communication with a small tube leading the oil to the piece of machinery. This small tube has to be airproof and ought to be carefully soldered in the bottom hole of the lubricator, as well as in the metal surrounding the piece of machinery to be lubricated. In order to facilitate the oil to run to the bottom of the lubricator, the latter is given a conical shape.

In preparing this absorbent, part of the granular mass of fibers becomes too fine to be employed for lubricating purposes. These fibers possess, however, the same absorbent power, and for this reason are particularly fit for chirurgical purposes, such as for absorbent bandages and dressings to be used in surgery previously prepared in antiseptical manner.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim- The herein-described method of lubricating machinery which consists in laying the saturated absorbent on a sieve in a lubricator covering it with a second sieve and covering the last-named sieve with a layer of oil, from which it is extracted to the pieces of machinery to be lubricated, by the exhaust caused by the rotation or other movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
